Shuttle



L. PAVIA SHUTTLE Filed Feb. 28, 1935 Nov. 5, 1935.

I INVENTOR Luzgv Pavia;

' musszs Patented Nov. 5, 1935 UNITED STATES PATENT OFFICE dclaims.

This invention relates to shuttles and has for an object to provide an improved construction wherein means are provided to distinguish between, right and left hand cops.

Another object of the invention is to provide an improved arrangement wherein the usual holding jaws are formed to provide a secondary. support for the cop holder in order to prevent'any sagging thereof.

An additional object is to provide an improved shuttle wherein the head is formed with apin adapted to be set either right or left and coacting with a right or left slotted cop holder, whereby only the right or left cop may be inserted accordingto the position of the cliitrolling pin.

In the accompanying drawing- Figure 1 is a top plan view of the device disclosing an embodiment of the invention;

Fig. 2 is a sectional view through Fig. 1 on the line 2-2;

Fig. 3 is a perspective view; slightly enlarged, of the cop holder supporting and holding jaws;

Fig. 4 is a perspective view of the head and part of the spindle shown in Fig. 1;

Fig. 5 is a perspective view of part of the cop holder shown in Fig. 1 and illustrating how the head is formed with a diagonal groove for accommodating the pin shown in Fig. 4;

Fig. 6 is a view similar to Fig. 4, but showing the pin extending at an opposite angle;

Fig. 7 is a view similar to Fig. 6 except showing a left-hand construction.

Referring to the accompanying drawing by numerals, l indicates the body of a shuttle, which on the outside is formed substantially of the usual shape, and provided with a spindle spring 2 acting on atransfer rod 3, which rests against the head I of a spindle 5. The head 4 is pivotally mounted on a pin 6 in the usual manner, and through rod 3 and spring 2 the head and the spindle are held either in the position shown in Fig. 2 or in a raised position. Anyabutment'gor support 1 is carried by the body I and acts'to limit the downwardly swinging movement of the spindle 5. In addition there is provided a special jaw structure 8, which also acts as a support for the spindle 5. The jaw structure 8 is provided with jaw arms 9 and M, d a transverse supporting connecting section M on which the cop holder l2 rests, thus providing a support therefor and for the spindle 5 which is in addition to the support I. The hea 4 is provided with a diagonal bore B in which the regulating pin it is positioned and clamped by a suitable bolt l5, whereby the pin may be removed whenever desired. The pin ll extends at an angle to the spindle 5 though it is arranged in a substantially parallel plane. This arrangement is provided in order that the slot or groove 56 in the head ll of the cop holder i2 may be engaged properly 5 by the pin it. For instance if the cop holder I2 has a right-hand wound cop thereon, it may be readily thrust on the spindle 5, while the pin it I will readily fit in the grooveli. However, if a readily be placed 15 upon the spindle 5' as th: ;i n li' is what may be termeda left-hand controlling pin and readily fits intothe groove ii. In this way the differently wound cops can only be placed in their correct shuttles.

It is customary in most looms to use cops wound in opposite directions and the threads therefrom are laid alternately as the loom functions. Usually the shuttles are differently colored to indicate right and left hand cops and this color scheme 25 maybe retained when using the respective pins l4 and I4 and associated parts. Therefore these parts will positively prevent the application of an incorrectly wound cop on a given spindle.

It is to be noted that in many spindles heretofore metal jaws are usedto overlap the head II, but in the present instance the jaw structure 8 is provided, which may be made of metal though it is preferably made from fiber or some other suitable material, and provides not only, jaws at opposite sides of the cop holder but at the bottom thereof. This jaw structure is preferably slid into suitable grooves l 8 and I9 formed in the body I, so that it will need no other form of fastening. After a cop has been properly positioned in the 4 shuttle, the same may be threaded through any of the eyelets 20, 2| and 22 according to circumstances. The eyelets just described form no part of the present invention but are used in certain shuttles to lead the thread from the shuttle. 5

I claim:

1. A shuttle, comprising a body, a spindle, a head for the spindle, means for plvotally mounting said head in the body, spring means acting on the head to hold the same in either of two 50 positions, a pin extending from said head in a plane parallel to the spindle but at an angle to the spindle, and a cop holder mounted on the spindle and formed with a head having a groove for receiving said pin.

2. In a shuttle for looms, a spindle provided with a spindle head, a pin carried by said head arranged in a plane substantially parallel to the spindle, said pin extending at an angle to the spindle and substantially across one end of the spindle, and a cop holder coacting with said spindle formed with a head; for accommodating said pin, whereby only cop holders having grooves at substantially the same angle as said pin can be used with said spindle.

3. In a shuttle of the character described, a spindle having a head, a cop holder mounted on said spindle and provided with a head, a pin extending from the head of the spindle, and a groove in the head of the cop holder positioned to receive said pin, said pin and groove being arranged in a parallel plane but at an angle to the spindle, said angle indicating the direction of winding of the yarn on the cop holder.

4. A shuttle comprising a body, a spindle, a head for the spindle formed with a recess and a threaded bore located centrally of the recess, means for pivotally mounting said head on said body, spring means acting on the head to hold the same in either of two positions, a pin extending from said head in a plane parallel to the spindle but at an angle to'the spindle, a screw 10 threaded into said threaded bore, the head or said screw pinching the end of said pin for clamping the same in place, and a cop holder mounted on said spindle and formed with a head having a groove for receiving said pin. 1
